Solo 433 is discontinued. The Maruyama MS0741 is still for sale. I have word that two disasters struck Japan last month, an earthquake and a typhoon. I have no idea if those disasters affected the factory that makes Maruyama equipment.
They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.
Benjamin Franklin 1775
Sell not virtue to purchase wealth, nor Liberty to purchase power.
